Funk took Soul and worked it on overdrive, adding Rock textures and focusing on one highly accentuated (but repetitive) groove. Stax and Motown were funky but James Brown, with his ultra-tight minimalist groove, and Sly Stone, with his upbeat, psychedelic Soul, get the credit for inventing the Funk. Those cats ran things until George Clinton and his Parliament/ Funkadelic outer-space army fused their sounds with Hendrixian guitars and Zappaesque concepts and comedy.
